ALBERT SAUER AND GUSTAV F. SIEVERN, OF PITTSBURG, PENNSYLVANIA, ASSIGNORS OF ONE-HALF TO CARL KAHLER, OF NE\V YORK, N. Y.

GAS-PRESSURE REGULATOR.

SPECIFICATION forming part. of Letters Patent No. 341,607, dated May 11, 1886 (No model.)

To all whom it may concern.-

Be it known that we, ALBERT SAUER and GUSTAV F. SIEVERN, of Pittsburg, in the county of Allegheny, State of Pennsylvania,

have invented certain new and useful Improvements in Gas-Pressure Regulators, of which the following is a specification.

This invention has reference to an improved pressure-regulator for natural and other gas,

so that the same is supplied for use at a uniform pressure.

In the accompanying drawings, Figures 1 and 2 are vertical central sections of two different constructions of our improved gas-p ressr 5 are regulator.

Similar letters of reference indicate corresponding parts.

A in the drawings representsavalve-casing, of cylindrical or other shape, which is connected with an inlet-pipe for the natural or other gas, and an outlet-pipe, b.

In the casing A is guided a slide-valve, B, of cylindrical or other shape, which is eon nected to a suitable balancing mechanism by which the maximum pressure is regulated.

The balancing mechanism consists of a weighted lever, 11, that is pivoted to the standard of a yoke, d, secured to the upper part of the casing A, and connected by a pivot-rod, d",

0 to the closed top of the slide-valve B, as shown in Fig. 1. The weight is adjusted to the pressure at which the gas is to be supplied. \Vhen the pressure of the gas is greater than the pressure ofthe weighted lever on the slide- 5 valve, the latter is raised, so that the inletport a is partly or entirely closed by a coinciding opening, a, at the lower part of the slide-valve, and thereby the supply of gas diminished or entirely interrupted. WVhen 0 the gas-pressure is reduced, the slide-valve is lowered by the action of the balancing-lever, so as to produce the registering of the opening a of the slide-valve with the supply-main a, and thereby the free passage of the gas reestablished. The outlet-port b is kept open by a recess, 2), of the slide-valve, so as to secure the free flow of the gas to the outletpipe.

By connecting the slide valve B by a rod,

6, with the valve 6 in the gas-main, as shown in Fig. 1, the supply of gas passing through the main is regulated by the valve 0 as the same is opened and closed more or less by the slide-valve B. The gas passes through the valve and regulating-main in the direction of 5; the arrows, Fig. 1, and serves, by the action oftheslidevalve B,to regulate the flow through the main.

In Fig. 2 the slidevalve B is arranged wit-ha ditferentbalancingmechanism. Adiaphragm, E, separates the upper part of the casing A from the lower part of the same, and forms a chamber, E, above the" diaphragm, which chamber is filled with air or any other suitable elastic medium, to which a'certain degree of pressure is imparted. The diaphragm E is connected by a rod, 6, with a central h u b of the open top part of the slide-frame. The slide valve is guided by an interior body, B, that communicates by openings f with the inletpipe a, but is separated by a partition, B from the outlet-pipe b, as shown in Fig. 1. By the increased pressure of the gas in the lower part of the casing A the diaphragm E and the slidevalve B are raised, so that the supply-openings f are partly closed: The decreasing pressu re of the gas reduces the pressure on the diaphragm and lowers the slide-vale B. When the gaspressure is greater than the pressure exerted on the diaphragm E by the compressed air in the chamber E, the slide-valve B keeps the supply-openings f entirely closed, and thereby the flow of gas interrupted, until the pressure of the same is reduced.

The advantages of our improved pressureregulator are that the pressure of the gas is automatically controlled by the gas itself, which pressure can be regulated as required by the use to which the gas is to be applied.

Having thus described our invention, we 0 claim as new and desire to secure by Letters Patent- In a gas-regulator, the casing A, having inlet and outlet pipes connected to the main,

a slide-valve, B, adapted to open or close the 5 supply-opening therein, and a weighted lever In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
